Title: Improved treatment of waste acids containing nitric acid
IPC: C01B21/46
Filed: 1938-05-31
Abstract: 515,429. Nitric and sulphuric acids. PAULING, H. May 31, 1938, No. 16257. Drawings to Specification. [Class 1 (ii)] In treating waste acids containing nitric acid and organic matter with steam in countercurrent, only that quantity of steam is employed which is necessary for heating the acid to the point of decomposition of the organic constituents and for expelling the nitrous gases, the nitric acid being left in the waste acid. Further nitric-acid may be added to the waste acid, if necessary for the complete decomposition of the organic constituents. The mixed acid thus freed from organic constituents and nitrous gases and consisting for example of nitric acid; sulphuric acid and water 'may be treated if desired under partial vacuum in a second stage with steam in counter-current in order to distill off and condense the nitric acid. Alternatively, the purified mixed acid, before the expulsion of the nitric acid, may'be subjected to evaporation and the vapour subjected to a rectifying concentration to recover a mixed acid containing say 65 per cent. of nitric acid and 10-12 per cent. sulphuric acid. By treating this acid with steam, 99 per cent. nitric acid may be recovered. If the concentration of nitric acid in the purified mixed acid is not sufficiently high to produce a concentrated nitric acid vapour on treatment with steam, the dilute nitric acid vapour evolved may be rectified in a separate countercurrent apparatus. This is effected by admitting to the counter-current apparatus into which the nitric acid and water vapour mixture enters at the bottom, a return of water from a condenser connected in sequence to the countercurrent device, the quantity of water corresponding to the quantity of concentrated nitric acid condensed in the counter-current device. The surplus water separated in the condenser is preferably employed in the absorption of the nitrogen oxides from the first stage.

Abstract: 634,520. Roller casting-machines. SOUDURE ELECTRIQUE AUTOGENE SOC. ANON. June 23, 1947, No. 16564. Convention date, July 2, 1946. [Class 87 (ii)] [Also in Group XXII] In a method of continuously casting bars, rods and wires, in which a pool of molten material is supported by cooled, leak-proof solid walls which move downwardly while progressively approaching and then separating from one another in at least two different transverse directions and forming between them at their closest point a passage the cross-section of which corresponds to that of the finished product, a single open jet 12 of molten material falls or is projected downwards on to the centre of the pool with sufficient velocity to maintain the pool in a state of agitation. In the embodiment described the rolls 1, 8¥ inches in diameter, revolve at 39 r.p.m., delivering approximately 60 feet per minute of 3/16 inch diameter wire. A crucible 5 is heated as by a high frequency induction coil 6, and oxidation of the metal prevented by floating slag or a reducing atmosphere such as town gas for carbon steels or nitrogen for nickel-chromium stainless steels. The rolls 1 are cooled by a water bath on the side away from the centre of the mill, each portion of the rolls being dried after wetting by a strong jet of air before contacting the metal again, to prevent explosions due to instantaneous vaporization. The temperature of the emerging product may be adjusted by varying the rate of pouring with or without varying the speed of rotation of the mill manually, or automatically by the use of pyrometric or photo-electric device.

Abstract: 255,220. British Dyestuffs Corporation, Ltd., Cronshaw, C. J. T., and Naunton, W. J. S. July 4, 1925. Diarylguanidines; cyanarylides.-Diarylguanidines are prepared by treating aniline or its homologues, e.g. toluidine, with liquid cyanogen chloride or bromide in the presence of water, and condensing the cyanarylides so obtained. In an example, aniline is run into a cold violently agitated mixture of cyanogen chloride and water, the stirring being continued and the mixture kept cold until the production of the insoluble cyananilide is completed; the temperature is then raised to about 90‹ C. for about 4 hours, giving a clear solution of diphenylguanidine hydrochloride which is run into hot caustic soda solution to obtain diphenylguanidine. In a further example, cyanogen bromide is employed, and is prepared by running the theoretical quantity of a solution of sodium, potassium, or other soluble cyanide slowly with thorough stirring into bromine covered with water and cooled to a low temperature in a closed pan. If the temperature is kept sufficiently low, solid cyanogen bromide is formed. The theoretical quantity of aniline &c. is then added, while still cooling and stirring, and the cyananilide formed. The temperature is then raised to 80-85‹ C. for about 3 hours or more, and the clear solution obtained run into hot caustic soda solution to give diphenylguanidine.
